Nintendo announced New Super Mario Bros. Wii just a month and a half ago at E3. They showed us the characters that were playable when they were demonstrating it. Characters that were used were Mario, Luigi, and two toads. Sadly to know for some, of what Shigeru Miyamoto provided in Nintendo Power, he stated a brief "that's it" response when he was asked if any more additional characters were going to be playable that wasn't revealed in the videos and screenshots.
